SNOW-GUARD FOR ROOFS.

To all whom it may concern Be it known that I, ALBERT DANZER, a citizenof the United States, and a resident of Hagerstown, in the county oflVashington and State of Maryland, have invented an Improvement inSnow-Guards for Roofs, of which the following is a specification.

My invention is a snow-guard constructed of plate metal anddistinguished by strength, durability, lightness, cheapness, andfacility of attachment to a roof. The details of construction of thesame are as hereinafter described, and illustrated in the accompanyingdrawing, in which- Figure 1 is a perspective view of the device appliedto a corrugated, metal roof. Fig. 2 is a cross section of the guard onthe line 2-2 of Fig. 1. Fig. 3 is a cross section of the guard and roofon the line 3-3 of Fig. 1.

The guard is formed of a single blank of rolled metal plate, preferablygalvanized iron. It consists of a body A which is of ornamental form,and parallel portions in the nature of arms B, which are formedintegrally with the body A and project from the lower edge thereof at anobtuse angle. A distinguishing feature of the guard is the form of thesearms B and that portion of the body where they join the same. That is tosay, the arms B are struck up in such manner that they have a centrallengthwise corrugation or convex rib, the same also extending into thebody A to a point 1) near the middle of the latter, as. shown in Fig. 1.By this means, the guard as a whole is greatly increased in rigidity,and the arms B being concave on the under side are adapted to fit onparallel ribs or corruga- Specification of Letters Patent.

tions of the roof X, as shown in Fig. 3. Another feature is thecorrugation and upward curve indicated at C in Figs. 1 and 3, wherebythe guard is further strengthened in the middle portion and due space isprovided for the roof rib that intervenes the two ribs to which the armsB are secured. The attachment of the guard to the roof is effected bymeans of rivets b, or equivalent fastenings.

The guard is preferably used alone or without a wooden bar or boardwhich is a common attachment of roofs. If, however, it be desired to usea bar or board, it may be readily secured to the upper side of the plateA by means of screws or other fastenings inserted through holes in theplate.

WVhat I claim is 1. The improved metallic roof-guard, consisting of anapproximately fiat body having parallel arms projecting from its loweredge, the body and arms being formed integrally, and arranged at anobtuse angle to each other, the arms having concavo-conveX corrugationsextending their entire length and also into the body of the guard, theends of said body projecting laterally beyond the arms, as described.

2. The improved metallic roof-guard, consisting of a flat bodyconstituting the guard proper, and integral arms projecting from thelower edge and arranged at an angle to the body and having lengthwisecorrugations, the lower edge of the body between the arms being curvedupward, as described.
